I '0 all whom it may concern:

Be it known that I, FRANK T. LIPPINOOTT, residing at Newark, in thecounty of Licking and State of Ohio, have invented certain new anduseful Improvements in Sash- Cord Connectors, of which the following isa specification.

. I My invention is an lmproved means for 4 quickly and automaticallyconnecting and disconnecting the sash cords from windows andsimultaneously securing the ends of said sash cords to the window framein a position where they may be quickly and effectively reconnected withthe window sash when desired. a

The invention is more specifically designed for use in connection with awindow of the type disclosed in my co-pending application filed October22, 1909, Ser. No. 524,073, of which application the present applicationis a divisional part.

In its more subordinate nature, the invention resides in those noveldetails of construction, combination and arrangement of parts, all ofwhich will be first described in detail and then be specifically pointedout in the appended claims, and illustrated in the accompanyingdrawings, in which Figure 1, is a central vertical longitudinal sectionof a window of the type disclosed in my co-pending application referredto with the invention applied. Fig. 2, is a detail central verticallongitudinal section showing the position of the parts when the sashcord is connected to the sash. Fig. 3, is a similar view showing theposition of the parts when the sash cord is automatically disconnectedfrom the sash and connected to the holder on the window frame. Figs. 4:,5 and 6, are detail perspective views of the fixed frame carried plateand the connecting link with the sash cord and the fixed window sashcarried plate which cooperates as indicated in Figs. 2 and 3. Fig. 7, isa detail view showing an alternative way of connecting the cord to theconnector.

Referring now to the accompanying drawings in which like letters andnumerals of reference indicate like parts in all of the figures, anysuitable sash balancing means may be provided for sustaining the weightof the window sash and continuously tending to pull upon the'sash cord9-to balance the weight of the window sash as stated. I

The sash cords or ribbons 9 at their free 1 ends are secured to doubleeye members 8, one end 8 of which joins with the sash cord or ribbon 9,while the other end 8 is adapted to connect with the window sash. Thedouble eye member 8 has a central brace or bridge portion 8 and is bentalong its line of bridge member so that the two eye por tions 8 8 willlie in different planes and form a fulcrum at the place 8, indicated inFigs. 2 and 3 of the drawings, for a purpose presently explained.

the window sash by screws 7 or other suitable means and the plates 6have hooks 6 opening outward toward the window frame. Secured in thegrooveof the window frame sectlon 1*, at suitable locations, preferablyat the position indicated in the drawings, are tongue plates l which arecountersunk into the frame and lie flush with the inclosed surfacethereof, the tongue plate l having downwardly directed tongues 4 whichproject into alinement with a hole 3, which may be bored or otherwiseprovided in the frame section 1 to receive the eye 8 of the double eyemember 8 to retain the sash cord in a definite position while the windowsashes are being removed. The tongue plates 4; may be secured by a screw5 or other suitable means, as indicated.

The window frame 1 includes the fixed grooved section 1 and the movablesections 1 which are hinged at 1 and in which sections the window sashes2 slide.

The manner of connecting the sash ribbon or cord with the window sashand with the tongue plate or fixed cord sustaining member form theessential features of my invention as by its use rapid connection anddisconnection between the sash cord and window sash may be made and atthe same time the sash cord or ribbon can be automatically shifted fromconnection with the window or vice versa, as conditions may require.

By particular reference to Figs. 2 and 3, it will be observed that whenthe parts are in their normal position, as shown in Fig. 2, the tensionon the sash cord 9 is directed upwardly in the direction of the arrow m,in Fig. 2, and by reason of the eye members 8"8 lying in differentplanes and bent at the bridge 8*, the bridge forms a fulcrum at 8causing the double eye member 8 to act as a lever, as it were, to movethe eye member sash into connection with the fixed holder,

Hook plates 6 are secured to the sides of 8 in the direction of thearrow'y, when connected with the hook 6.

In order to disconnect the sash cord 9 from the window sash, the sash ismoved until the hook 6 is opposite the hole 3 and the tongue l as shownin Figs. 2 and 3 of the drawings. The operator then grasps the sash cordor ribbon 9, adjacent to the eye member 8, or he grasps the upper end ofthe eye member 8" and pulls downwardly on the sash cord or ribbon 9 inthe direction of the arrow in Fig. 3 and inwardly in the direction ofthe arrow .tv in Fig. 3, which causes the eye member 8' to move in thedirection of the arrow y in Fig. 3 and automatically and simultaneouslydisconnect the eye member 8 from the hook (3 and move it into the holeinto engagement with the tongue t to hold it in that position until itis again desired to connect the sash cord with the window sash, when themovements just described are reversed. Thus it will be seen that withone action the sash cord is disconnected from the window sash andconnected with the fixed holder of the frame to be in position forreconnection with the window sash when desired. Furthermore, member 8,as shown and described, the tension on the sash cord 9 when the partsare positioned, as shown in Fig. 2, (it being understood, of course,that the invention is applied to each side of the window) will serve tohold the sash centered in the frame and reduce considerably the frictionof the sides of the window sash in the grooves, thus making it easy toraise and lower the window sash and prevent chattering of the windowsash in the grooves during the action of raising and lowering.

In this application I make no claim to the specific construction of thewindow per cc, as that forms the subject-matter of my originalapplication.

From the foregoing description taken in connection with the accompanyingdrawings, the complete tamstruction, operation and advantages of myinvention will be readily understood by those skilled in the art towhich the invention appertains.

hat I claim is:

1. In a window having a frame and slidable sashes, the combination withsash cords for sustaining said sashes at each side, of a single means ateach side of the window for connecting the respective sash cords withsaid sashes and .sinniltaneously centering said windows in said frame.

2. ln a window construction, a frame and window sashes slid-able thereintogether with sash cords for counterbalancing said sashes, sash cordconnectors removably connecting said St sh cords with said sashes, saidsash cord connectors having provisions in virtue 0 in Fig. a,

by constructing the.

of which the tension of the sash cords will center said sashes in theframe.

3. In a window construction, a window frame having window sash receivinggrooves, sashes slidable in said grooves, sash cords under tension forsustaining said sashes, a

ed sash cord holder secured to said window frame at each side of eachsash, said holders each having a tongue portion and said frame having ahole adjacent to each tongue portion, a hook member secured to each sashat each side and havin the opening of the hook adjacent to the frame, aconnecting member carried by each sash cord for engaging the respectivehook members and the respective fixed sash cord holding mem bers attimes, said comiecting members having portions lying in dilfcrent planesto provide a fulcrum bearing, in virtue of which when said hook membersare in alinement with the respective tongues of said fixed holders, saidconnecting members may be disconnected from said hook members andsimultaneously connected with said fixed holding men'ibers and viceversa, and when said hook members are out of alinement with therespective holding members said connecting members will be held fromdisconnecting with said hook members, substantially as shown andescribed.
